Integration

um.. i dont know how they do it where you live.. or where you heard your information on plus sizing rims.. but when go to wider rims, they generally give you narrower tires so that it equals the same total wheel (rim/tire) diameter as stock. For example, here is a pic of one of my stock wheels next to my 17's on each of my tegs. What do ya know.. exactly the same hight.8urcivic said:yea...im saying i dont car what anyone says.....if you upsize the wheel on anycar....its not gonna improve handling...i mean your upping your wheel size by 2 inches.....depending on tires size...i would say on average thats still a good 1 to 1.5 inches taller than you should be........easier said........a taller car cannot out handle a lower car.....unless....the car is below its lowing point....now personally i would love to go lower....but them it would bind up even more when cornering hard......so stock size wheels......maybe a little wider......FTW!!!

Ride hight, is NOT increased, therefore there is no performance loss in the type that you mentioned. The main loss in performance would be the rim being heavier than the stock rim. Based on physics, it will take more force/energy to start a heavier wheel turning as well as more force to bring a heavier moving wheel to a stop. So compared to a bone-stock integra, an integra with everything stock except for bigger/heavier rims will accelerate slower and take longer (or a higher amount of brake wear) to bring to a stop from any given speed. Thats why forged rims are expensive, because you can get larger rims, i.e. 17 & 18", that weigh the same as, or less than, our stock 15" rims due to the process of forging. So you get the benefits of larger rims with none of the normal drawbacks to accel/decel rates and increased unsprung weight.
There IS performance gain with handling due to the rim being wider from side to side. A wider wheel offers more area that is available for friction. This will allow the car's grip to improve while turning because the contact area with the ground has been improved. Also with the narrower tire sidewall, the tire flex is reduced adding more stability during cornering.
